Question

Use the coordinates of the labeled point (3, -4) to find a point-slope equation of the line.

A. Y-4=-3(x+3)
B. Y-4=3(x+3)
C. Y+4=3(x-3)
D. Y+4=3(x-3)

Answer 1

C. y+4=-3(x-3) is the right Answer Just got it right

Answer 2

C or D since they are the same

Explanation:

The point slope form of a linear equation is
`y - y-1 = m(x-x_1)`. Substitute (3,-4) into the form.

`y --4 = 3(x-3)\\y + 4 = 3(x-3)`
